Stable Isotopes in the Critical Zone: Methods, Applications, and Process Interpretations
Session ID#: 250488
Session Description:
Natural abundance and enriched stable isotopes are exceptional tracers, contributing to a deeper comprehension of the transport and transformation of water, carbon, and other elements. Their use has led to novel insights into the Critical Zone and the soil-plant-atmosphere continuum. Furthermore, new methodological and technological developments have facilitated using stable isotopes to trace system exchanges and feedback processes on many levels, from micro- to regional-scales. With such advancements, new opportunities and perspectives have arisen, fostering increasingly interdisciplinary approaches to Critical Zone processes. This session aims to bridge bio-hydro-geo-eco communities by showcasing studies that use stable isotopes to enhance our understanding of the Critical Zone and/or to advance relevant stable-isotope methods and application techniques. We particularly welcome studies that transcend disciplinary boundaries and adopt innovative approaches to improve process understanding. Additionally, this session encourages presentations of opinions, perspectives, and syntheses that guide the Critical Zone stable isotope community.
